If risk is huge, the profit was also huge. However, if you will not take such kind of risks in your life, then it will not be possible for you to make any significant earning. But always be careful, because sometimes you maybe choosing the wrong coins that you are buying.
I do not agree with the statement. Risk is not necessary to earn big profits. You have the data and the market with you. You can easily evaluate a good and profitable coin with low risk and stable prices. This will enable you earn good money with low or no risk and enjoy the bounties. In crypto, there are certain coins having a bit risk but huge profit in the end. Rational individuals prefer the future benefits over risk and enjoy the bounties with risk.
